MACHINE FOR ATTACt-HMG BUTTONS.

SPECIFICATION forming part oi' Letters Patent No. 385,734, dated July l0, 1888.

Application tiled October 2G, lun?.

To @ZZ whom, it may concern:

Beit known that I, EUGENE H. TAYLOR, of Lynn, in the county ot' Essex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Attaching Buttons, of which the following, taken in connection with the accompanying drawings, is a specilication.

My invention relates to machines for attaching buttons to leather, cloth, or other flexible material, and to that particular class of such machines in which the button-fastening staples, with the buttons attached, are automatically fed along a raceway in a row or continuous line, and the lower staple is separated from said row or line and driven into and clinched to the material; and it consists in certain novel features of construction, arrangement, and combination of parts, which will be readily understood by reference to the description ot' the drawings, and to the claims to be hereinafter given, and in which my invention will be particularly pointed out.

Figure l of the drawings is a sectional side elevation of a machine illustrating my invention, with the anvil in position for setting the staple. Fig. 2 is a central vertical section ot' a portion ot' the upper part ot' the machine, taken in the same plane as the section of the lower part of Fig. l, with the parts in position for feeding the staple to the position for being set. Fig. 3 is a plan with a portion of the base-flange and raceway broken away. Fig. 4 is a partial front elevation of the raceway, with a portion of one front plate broken away t0 show the staple-arresting spring-stop. Fig. 5 is transverse section through the raceway and driver-stock on line m x on Figs. 1 and 2. Fig. 6 is a rear elevation of the button-separating spring-stops. Fig. 7 is a horizontal section of the raceway on line y y on Fig. l', and Fig. 8 is a rear elevation of a portion of lower end of the driver-stock and its driver.

In the drawings, A is the fratrie of the head of the machine, provided with the laterallyprojecting arms A and A2 and base-flange A3, by which it may be secured upon a supporting column or bench (not shown) in any wellknown manner. The arms A' and A2 are Serial No. 253,439. (No model.)

fork ed at their front or outer ends to receive the driver-stock B, pivoted to the arm A at a in such a manner that its lower end may be moved laterally to move the driver end b into and ont of the pat-h ot thc button fastening staples.

To each side of each of the arms A and A2 is secured a plate, c, provided at its front end `with the iuwardly-projecting lip c', said lips forming guiding bearings upon which theraceway-bar C may be moved vertically. The bar Chas formed in each edge thereof a longitudinal groove, d, to tit the lips c, and in the center ot' its front face with a rectangular groove, e, of a width and depth corresponding substantially to the width and thickness of the button-fastening staple, and has secured to its front face the two thin metal plates e', the inner edges of which project over and cover a portion of said groove e, but leaving a space between said inner edges sulticient for the tree passage ofthe eye ot" the burton, all :as shown in Figs. 4 and 5.

The raceway-bar C has its lower end slotted through its back to permit the passage through said back ot' the augularly-projecting setting tool or driver Z), as shown at b', Figs. l, 2, aud 4, and so mounted upon the guiding-lips that it may be moved vertically against the tension of the springs D D, which bear upon the laterally-projecting pinsff, set in said bar, and tend to hold said bar C in the depressed position indicated in Fig. 2, its downward movement being limited by the upper ends of the grooves d coming in contact with the upper ends of the lips c upon the upper plates, c, or by any other suitable stop.'

E is the anvil, firmly secured to the free end of the lever F, pivoted at g to the frame A, and having pivoted thereto the rod G, the lower end of which is pivoted to a treadle (not shown) so arranged that by the operator placing his foot upon said treadle and pressing the same downward the anvil E will be moved upward into contact with the racewaybar C and move said bar upward into the position indicated in Fig. 1.

rIhe upper end of the slot b is cut oblique to the raceway-groove to act upon the upper surface ofthe obliquely-projecting driver b, to

move said driver backward out of the raceway-groove when said bar C is moved downward, and said slot b' is provided upon each side with the oblique shoulder h, which acts upon the lower end of the driver to move the saine toward the front and into line with the raceway-groove c when the bar C is moved upward by the upward movement of the anvil E.

To the back side of the raceway-bar C are secured the two springs fi and i, shaped and arranged as shown in full lines in Fig. 6 and in dotted lines in Fig. 1, each of said springs being provided with a pin, i?, which projects through a slot, j, in the bar C, extending forward to near the front side ofthe groove e when said spring is in its normal position, as indicated in Fig. 2.

The driver stock B has formed in its front side a rectangular chamber or recess, B', which extends nearly its whole length, and into which said springs i and li project, as shown in Figs. 2 and 5.

Two pins, k and k. are set in said driverstock so as to extend across the chamber or recess B in such positions that the curved up` per end of the spring t' will strike the pin t when the bar C is moved upward, and thus retract the pin fig of said spring i?, thereby re.

leasing the column of buttons and staples rest.- ing thereon and allow said buttons and staples to descend a distance equal to the diameter of a button, when they will be arrested by the pin i2 of the spring fi; and when the bar C is again moved downward the spring i will assume its normal position, and its pin will be projected between the eyes of the lower button and the one next above it, and the curved lower end of the spring z" will come in contact with the pin k and be moved toward the rear, thus withdrawing its pin i2 from beneath the eye of the lower button of the column of buttons, when said button and its attached staple will descend the groove e until the lowerends of the staple come in contact with the inclined shoulders Z on the spring or yielding stops m im (Shown in Fig. 4.)

H is a spring fitted to a socket formed for the purpose in the arm A2, the tension of which serves to press the lower end of the driverstock toward the raceway-bar C.

The operation of my invention will be readily understood by reference to the foregoing without further description here.

Vhat I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a machine for attaching buttons, the conibination herein described of a movable anvil, a vertically-movable raceway-bar having a slot cut through its back near its lower end. and a pivot'ed driver-stock provided with a driver projecting obliquely therefrom and constructed and arranged to be vibrated about its pivot by the reciprocations of said raceway, whereby said driver is projected into and retracted from the path ot' descent of the button-fastener staples.

2. The combination herein described of a vertically-movable raceway, a pair of buttonseparating spring-stops secured to and movable with said raceway, a pivoted driver and stock provided with pins constructed and arranged to alternately operate said spri lig-stops, andan anvil mounted upon the free end of apivoted lever constructed and arranged to be vibrated to force the work upon the button-fastener and clinch said fastener by moving the raeeway upward.

3. The combination of the movable anvil E, the vertically-movable raceway C, the pivoted and laterally-movable driver B b, provided with the pins li: and la, and the spring-stops i i, z" fr, and m m, all constructed and adapted to operate substantially as and for the purpose described.

In testimony whereof I have signed my name to this speci lication, in the presenceof two subscribing witnesses, on this 19th day of October, A. D. 1887.

EUGENE H. TAYLOR.
